You can get away with allot with stock needles. But I have yet to find a good enough mid range and the gap between pilots and main jets have me now playing with needles.
I found I have 150s and 45s. Can't believe I couldn't remember. going to play with some stuff cause with my set up that should be rich... i just might be too picky. I dont want or need like dyno ran perfection, i just dont want engine damage.
